, that can'be formed completely out of one sheet of metal by a singlepunching operation. 1

With the foregoing objects in view, my invention resides in the novelmanner of forming the device and in the shaping of parts thereof so thatthey will serve as a support for the can to be perforated and as a guardfor sustaining the can in position when the punch pierces the hole inthe upper end thereof.

In accomplishing these and other objects of the invention, I haverovided the improved details of construction, the preferred. forms ofwhich are illustrated in the accompanying drawings wherein Figure 1 is aplanview of the punched out blank from which the device is formed.

Figure 2 is a perspective view of the device in operative position.

. Referring more in detail to the draw- 1n si designates the flat blankof sheet metal from which the device, as shown in Figure 2, except thepunch lever, is formed, the blank being formed as shown by a singlepunching operation. The blank comprises a flat endportion 2, adapted toserve as the mounting base for the perforating device and which isalmost separated from the other end portion 3 of the blank by slots 4- 1which lead into the blank from opposite side edges leaving only a narrowcentral neck portion 5 whereby the parts 2 and 3 are joined. The part 3is adapted to serve as a positioning su port or guard for the can beingperforate and also as a mounting for the punch or perforating lever 6pres e'ntly described.

Extending centrally from the upper end of the portion 3 of the blank arestandards, or extensions, 7-7, provided at. their ends with alignedapertures 8 for receiving a screw, or bolt, 9 whereby the punch lever 6,as shown in Figure 2, is pivotally mounted.

The punch lever is formed from a single piece of metal that may bestamped out of the metal sheet atthe same operation when blank 1 ispunched, and it comprises an outer end portion 10, and, on its underedge, has two downwardly projecting piercing oints 11-11, adapted forpiercing the en Wall of a can adjacent its opposite edges.

A hole, 12, is provided centrally in the base 2 for receiving a screw,or other means for securing the device in place-upon a table or otherform of support. c

When-the metal blank has been formed in themanner described, the upperportion 3 is bent at the neck portion 5 at a right angle to the baseportion 2, as is illustrated in Figure 2, and the opposite side portionsof the part 3 are curved radially inwardly to form wing uards thatreceive the can therein; the radial curvature of the wings to be slihtly greater than that of a condensed mi k can for whichthe device isintended. The extensions 7,7 that form the support 3 for the punch leverare bent inwardly in s aced-apartrelation to receive one end of te'lever 6 which is pivotally attached thereto by the bolt 9, as abovedescribed.

In use, the can, as indicated at 15 in dotted lines in Figure 2, isplaced upon the base 2 within the wing guards of the upright-portion 3which serves to retain the can properly in osition. The punch lever isthengpressed own by the handle 10 and the oints 11 caused to pierce-theupper end of t e can.

' Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent, is:

A device of the class described comprising a single metal piece that isbent at right angles forming a base and an upstanding portion and havingthe side edges of the upstanding 1 portion severed from the base andcurved inwardly to partially encompass a can placed in the base.extensions formed on the 11' per end of said upstanding por- (ill tionand entin spaced apart, parallel relation, and a punch lever pivotallyattached at one end between said anges and providcd with piercing-pointson its under edge adapted to pierce holes in the top of the canwhenpositioned u on said base.
